Patented June 29, 1937 PATENT OFFICE DUSTPAN DUMP FOR CARPET SWEEPERS Wadsworth Bissell, Grand Rapids, Mich., assignor to Bissell Carpet Sweeper Company, Grand Rapids, Mich.

Application September 17, 1935, Serial No. 40,943

4 Claims.

This invention relates to improvements in dustpan dump for carpet sweepers.

First, to produce a new and improved type of dumping mechanism for the dust pans of .carpet sweepers.

Second, to provide such a means which is easily operated and which is inconspicuous.

Third, to provide such a means which may be economically installed on a carpet sweeper.

Further objects and advantages pertaining to details and economies of construction and operation will appear from the description to follow. A preferred embodiment of my invention is illustrated in the accompanying drawing, in which:

Fig. 1 is an end view partly in section of a carpet sweeper showing my pan dumping arrangement with the parts in dumping position.

Fig. 2 is a sectional view through a carpet sweeper embodying my invention showing the dust pans in closed position.

Fig. 3 is a sectional view taken on line 3-3 of Fig. 2 showing the ends of the carpet sweeper embodying my invention..

In the drawing, I is a conventional carpet sweeper casing having ends 2 and 3, oor wheels 4 and brush 5, all of ordinary carpet sweeper construction and which form no part of this invention and need not be described in detail.

Dust pans 6 substantially identical with those shown in Patent No. 1,741,163, issued to'Ira J.

Owen, Dec. 31, 1929, for Carpet sweeper, are pivoted at I between the ends 2 and 3 of the carpet sweeper casing. A bent spring 8 substantially similar with that shown in the above mentioned patent extends between the pans 6, being pivoted at 9 in the pans and having an upwardly extending loop Ill which is raised to dump the pans.

The spring serves to maintain the pans in the closed position shown in Fig. 2 as well as to dump the pans by its raising movement.

In the end 2 of the casing is a vertically extending slot II. This slot is positioned with its lower end adjacent but below the upwardly extending loopv II) of the spring 8. A handle comprising a bail I2 is provided. It is pivoted at I3 in a conventional manner in the end 3 of the case and has a nib I4 which extends through the slot II and under the upwardly extending loop Ill of the spring 3. An annular groove I5 serves to engage the spring and prevent its slipping off the bail.

When the pans of the sweeper are in closed position, the nib I4 rests at the bottom of the slot II and is held yieldingly in place by the spring 8. A raising of the handle bail I2 and with it the nib I4 raises the loop I 0 of spring 8 and causes the dust pan 6 to dump. 'I'his may be accomplished by holding one hand against the top of the carpet sweeper casing and pulling on the handle bail as will be obvious. 4Releasing the bail causes the dust pans to be forced back to closed position by the spring 8, which at the same time tends to yieldingly hold the nib I4 in the bottom of the slot I I.

It will be appreciated that it is desirable to have the pivot I3 and the nib I4 in line when the pans are closed so as to assure even pressure on the sweeper during use. It will be appreciated that the pivot I3 could be provided with a nib somewhat similar to the nib I4 to engage under the spring I 6, which is substantially similar to the spring 8, but that it is not necessary in ordinary constructions to have such an arrangement.

It will be realized that with this particular construction I eliminate many parts of the dumping apparatus as shown in the above mentioned patent to Owen and provide a very neat appearing sweeper in that the dumping mechanism is all concealed from View.

I Wish to claim my invention both broadly and specifically as pointed out in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is: 30

1. A carpet sweeper casing, dust pans pivoted between the ends of said casing, means for holding said dust pans closed and for dumping said dust pans comprising a spring extending between the pans and having an upwardly extending loop which is raised to dump said dust pans, a vertical slot in one end of the casing having its lower end adjacent and below said upwardly extending loop when the pans are in closed position, and a handle including a bail having a nib pivoted in and extending through said vertical slot and under said upwardly extending loop whereby when the dust pans are closed, the nib of the bail is held yieldingly in the bottom of the slot and whereby the pans may be dumped by an upward movement of said nib.

2. A carpet sweeper casing, dust pans pivoted. between the ends of said casing, means for holding said dust pans closed and for dumping said dust pans comprising a spring extending between the pans and having an upwardly extending loop which is raised to dump said dust pans, a vertical slot in one end of the casing, and a. handle including a bail having a nib pivoted in and extending through said vertical slot and under said upwardly extending loop whereby the* pans may be dumped by an upward movement of said nib.

3. In a carpet sweeper casing having dust pans therein, a vertical slot in one end of said casing, a handle including a bail having a nib pivoted in and extending through said slot, and means engageable by said nib for dumping said dust pans when said nib is moved in said slot.

4. In a carpet sweeper having a casing for dust 10 pans therein, the combination of a sweeper operthe handle will dump said dust pans.
